If you didn't already know the Spike Conical is a unitank! This means it is designed to handle pressures up to 15psi. This capability allows you to add 15psi of pressure needed to carbonate your beer before transferring to your keg. This will reduce carbonation times from upwards of a week down to less than 24hrs.

Our carb stone is designed to attach to the outside of the racking port butterfly valve. This means the carb stone can be installed when you need it and won't be sitting inside the tank during the entire fermentation process. This eliminates the chance for the stone to become clogged. It also has a protective stainless housing which prevents damaging the very brittle 'stone'.

Love it...but....

I think the stone is great, and the way it works on the CF is so simple! The only problem is....if you don't have the cooling system you cannot get to the proper PSI for carbonation.

24 hours to perfectly carbonated beer

Just finished using the carb stone from Spike. Worked excellent! Had my beer perfectly carbonated in ~24 hours. Just simply followed their advice on adjusting for wetting pressure. Spike really provides comprehensive, easy to follow directions for all their gear!
